Two railings 3 are mounted on the bed frame assembly 1, one of which has a set of connecting rings 301 fixedly mounted. A set of pull ropes 203 are fixedly mounted on the cart 2, moving through and around the connecting rings 301. One end of the pull ropes 203 has a pull ring 204 fixedly mounted. Several tension springs 4 are arranged between the cart 2 and the bed frame assembly 1. Users can control the cart 2 to slide on the bed frame assembly 1 by pulling the pull rings 204 on the soft pad 201, causing the tension springs 4 to deform, thereby performing various stretching, pulling, and strength training exercises to enhance core stability, flexibility, and muscle endurance.

[0033] Please see Figures 1-3 The bed frame assembly 1 includes two hinged frames 101 that can be folded to achieve the folding and storage function of the bed frame assembly 1. Each frame 101 has a sliding groove that slides with a sliding trolley 2. Two support plates 102 are fixedly mounted on one side of each frame 101. An n-shaped support frame 103 is hinged between the two support plates 102. Two casters 104 are movably mounted within the n-shaped support frame 103. An adjustment component 5 is provided on the n-shaped support frame 103 to adjust the position of the two casters 104. The adjustment component 5 includes two limiting grooves 501 set on the n-shaped support frame 103. An adjustment plate 502 is slidably arranged between the two limiting grooves 501. A threaded rod 503 is fixedly arranged on the top of the adjustment plate 502 and is slidably inserted into the n-shaped support frame 103. An adjusting nut 504 is rotatably arranged on the n-shaped support frame 103 and is threadedly rotatably connected to the threaded rod 503. Two universal wheels 104 are fixedly arranged at the bottom of the adjustment plate 502 and a locking structure is provided in the universal wheels 104. The adjusting nut 504 is rotatably connected to the threaded rod 503. When the adjusting nut 504 rotates, it can drive the threaded rod 503 to slide within the n-shaped support frame 103, thereby allowing the adjusting plate 502 to slide within the limiting groove 501, enabling the caster wheel 104 to move. When the caster wheel 104 is retracted into the limiting groove 501, the bed becomes stable. When the caster wheel 104 leaves the limiting groove 501, the bed can be moved easily.

[0034] Please see Figures 1-3 , Figure 6Two railings 3 are rotatably mounted on two frames 101. Braking components 6 are provided on both sides of the frame 101 and on one side of one of the support plates 102. The braking components 6 on both sides of the frame 101 brake the rotation of the railings 3, and the braking component 6 on one of the support plates 102 brakes the rotation of the n-shaped support frame 103. The braking component 6 includes a turntable 601, and the turntable 601 on the frame 101 is fixedly connected to the railing 3. The turntable 601 on one of the support plates 102 drives the n-shaped support frame 103 to rotate. The turntable 601 is provided with a movable groove, and a locking rod 602 is movably connected through the turntable 601 and the locking rod 602 movably passes through the movable groove. One end of the locking rod 602 is fixedly connected to a handle 603. A spring 604 is sleeved on the locking rod 602, and one end of the spring 604 is fixedly connected to the movable groove, and the other end is fixedly connected to the handle 603. The locking rod 602 on one side of the frame 101 is interlocked with the frame 101. The locking rod 602 on one side of one of the receiving plates 102 is interlocked with one of the receiving plates 102. If it is necessary to rotate the railing 3 or the n-type support frame 103, the corresponding handle 603 needs to be pulled to disengage the locking rod 602 from the locking point, thereby preventing the railing 3 or the n-type support frame 103 from being braked and allowing the railing 3 or the n-type support frame 103 to rotate. After rotating to a suitable angle, the handle 603 can be released. Through the elastic force of the spring 604, the handle 603 can be pulled to engage the locking rod 602 with other locking points, thereby braking the rotation of the railing 3 or the n-type support frame 103 and determining the angle of the railing 3 or the n-type support frame 103.

[0035] Please see Figure 1 , Figure 5 Both ends of the tension spring 4 are provided with connecting components 7, which are respectively connected to the sliding cart 2 and one of the frames 101. The connecting components 7 include connecting blocks 701 fixedly mounted on the tension spring 4. The connecting blocks 701 are provided with T-shaped through slots 702, which movably pass through the three sides of the connecting blocks 701. Two oppositely arranged connecting hooks 703 are slidably mounted in the T-shaped through slots 702. Each of the two connecting hooks 703 is provided with a storage slot. A spring 704 is fixedly mounted between the storage slots of the two connecting hooks 703. The sliding cart 2 and one of the frames 101 are provided with connecting slots for the two connecting hooks 703 to be movably inserted and locked. When the tension spring 4 needs to be installed between the sliding trolley 2 and one of the frames 101, the two connecting hooks 703 need to be moved toward the spring 704 so that the two connecting hooks 703 can be inserted into the corresponding connecting slots. After insertion, the two connecting hooks 703 can be released. Through the elastic force of the spring 704, the two connecting hooks 703 can be pushed, so that the connecting hooks 703 can be engaged with the connecting slots, thus completing the installation of the tension spring 4.

[0036] Please see Figures 1-3The sliding trolley 2 is provided with two locking components 8, which are locked together with another frame 101 and brake the sliding trolley 2 to slide on the frame 101. The locking components 8 include a connecting clip 801 that is slidably limited on the top of the sliding trolley 2. A locking block 802 is hinged in the connecting clip 801 through a connecting shaft. A handle 803 is fixedly provided on one side of the locking block 802. A torsion spring is sleeved on the connecting shaft. One end of the torsion spring is fixedly connected to the connecting clip 801, and the other end is fixedly connected to the locking block 802. When the locking block 802 does not brake the sliding trolley 2, it locks together with the sliding trolley 2. When the locking block 802 brakes the sliding trolley 2 to slide, it locks together with the other frame 101. The torsion spring provides torque to the locking block 802. When it is necessary to brake the sliding carriage 2, first slide the sliding carriage 2 to a suitable position on another frame 101, then pull the handle 803 to rotate the locking block 802, so that one end of the locking block 802 leaves the sliding carriage 2. Then the connecting clamp 801 can be slid. After the connecting clamp 801 moves to a suitable position, the handle 803 can be released. Through the torque of the torsion spring, the locking block 802 can be rotated to the initial position, so that one end of the locking block 802 engages with the other frame 101, thereby braking the sliding carriage 2.

[0037] Please see Figures 1-4 Each of the two frames 101 is equipped with two limiting components 9. The limiting components 9 engage with the opposing frame 101 and brake the rotation of the two frames 101. The limiting components 9 include an adjustment groove 901 on the frame 101. An L-shaped limiting block 902 is slidably mounted on the upper limit of the adjustment groove 901. The L-shaped limiting block 902 moves through the frame 101 it is connected to and engages with the corresponding frame 101. The L-shaped limiting block 902 and the frame 101 it is connected to are fixed in position by bolts 903. When the two frames 101 are not in a folded state, one end of the L-shaped limiting block 902 needs to be moved into the corresponding frame 101 to engage, and then the L-shaped limiting block 902 is fixed by bolts 903, thereby preventing the two frames 101 from folding.

[0038] The working principle of this utility model:

[0039] When folding the Pilates core training bed, first pull the handle 603 on one of the support plates 102, causing the locking lever 602 to disengage from one of the locking points on the support plate 102. Then, rotate the n-shaped support frame 103 until it is parallel to the frame 101 and stops rotating. Then, release the handle 603. Through the elastic force of the first spring 604, the locking lever 602 can be engaged with the other locking point on one of the support plates 102, thereby stopping the rotation of the n-shaped support frame 103. Next, operate the braking component 6 on the railing 3 in the same way, so that the railing 3 rotates until it is parallel to the frame 101 and stops rotating, and the rotation is stopped by the braking component 6. Then, move the two connecting hooks 703 towards the second spring 704, so that the two connecting hooks 703 are not engaged with the connecting groove. Then, pull the two connecting hooks 703 out of the connecting groove. Remove the tension spring 4 from one of the frames 101 and the sliding cart 2, then slide the sliding cart 2 to a suitable position on the other frame 101. Pull the handle 803 to rotate the locking block 802, causing one end of the locking block 802 to disengage from the sliding cart 2. Then, slide the connecting clamp 801. After the connecting clamp 801 moves to the suitable position, release the handle 803. The torque force of the torsion spring will rotate the locking block 802 back to its initial position, causing one end of the locking block 802 to engage with the other frame 101, thus braking the sliding cart 2. Then, rotate the bolt 903 to disengage it from the frame 101. At this point, the L-shaped limiting block 902 can be slid, preventing it from engaging with the corresponding frame 101. Then, use the bolt 903 to fix the L-shaped limiting block 902 entirely within the adjusting groove 901. At this point, the two frames 1 can be folded as follows: Figure 3 As shown.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
